Information about Family

Compact and extra flat.

This extra flat LED driver offers flexibility at choosing compatible LED modules due to the very wide operating window. Some other highlights include the capability for DC-input, the suitability for emergency installations and the optional cable clamp that allows independent installations and trough-looping.

Ecodesign regulation information:
Intended for use with LED modules.
The forward voltage of the LED light source shall be within the defined operating window of the control gear in all operating conditions including dimming if applicable.

Separate control gear and light sources must be disposed of at certified disposal companies in accordance with Directive 2012/19/EU (WEEE) in the EU and with Waste Electrical and Electronic Equipment (WEEE) Regulations 2013 in the UK. For this purpose, collection points for recycling centres and take-back systems (CRSO) are available from retailers or private disposal companies, which accept separate control gear and light sources free of charge. In this way, raw materials are conserved and materials are recycled.
